🗞️ Driving the news: Physicists at JILA, University of Colorado Boulder, have made a breakthrough toward building a “nuclear clock” by measuring the nuclear “tick” of a thorium atom for the first time
• This ultraprecise clock, rooted in atomic nuclei rather than electron oscillations, could surpass the accuracy of even today’s best atomic clocks
• The discovery was made possible by a specialized laser and represents the first tangible progress on a concept proposed two decades ago

🔭 The context: Current atomic clocks, based on the oscillations of cesium and strontium atoms, provide precise measurements that are essential for GPS and financial markets, but a nuclear clock would take accuracy even further
• A thorium-based nuclear clock could provide more stability, as the nucleus is less influenced by external factors that affect atomic clocks
• Advances in laser technology and recent experiments at CERN made the discovery of this “tick” possible

🌍 Why it matters for the planet: Ultraprecise timekeeping tools like nuclear clocks can deepen our understanding of physics, aiding in the exploration of phenomena like dark matter and gravitational waves
• With potential applications for predicting volcanic eruptions and testing fundamental constants of physics, nuclear clocks could transform both scientific research and global technologies reliant on timing accuracy
• Such a clock could redefine time standards and improve technology from navigation to quantum computing

⏭️ What's next: The team will continue refining the “tick” measurement to develop a prototype nuclear clock
• This clock will allow physicists to conduct new experiments on constants like the fine-structure constant, testing if it shifts over time—a potential indicator of “new physics”
• If successful, nuclear clocks could eventually be deployed for practical uses where ultraprecision is critical

💬 One quote: "The paper opens a realistic way to build a nuclear clock. … From dream, it becomes reality” – Olga Kocharovskaya, Physicist, Texas A&M University

📈 One stat: The new thorium nuclear clock would tick at a rate 4.707072615078 times faster than the most precise strontium atomic clock
